Is there a way to comment SQL queries in Sparx Enterprise Architect?

Question

Is there a way to comment SQL queries in Sparx Enterprise Architect e.g. /* SQL Query */. This is so that I can run different queries without having to delete previous queries.

Answer 1

The query editor recognizes both -- and /* */, but neither seems to actually work. So no.

Best way is to store your queries as searches.

Answer 2

Enterprise Architect's #DB=# macro works well for comments in SQL Model Search queries.

#DB=COMMENT# <comment text> #DB=COMMENT#

For example, to explain why a query differs for JET4.0 vs. MYSQL versions:

SELECT distinct o1.ea_guid AS CLASSGUID,
    o1.name AS Name,
    o2.name AS Subtype,
    o3.name AS Sub2,
    o4.name AS Sub3,
    o5.name AS Sub4
#DB=COMMENT# JET does not allow mixing LEFT/INNER JOINS #DB=COMMENT#
#DB=JET#
FROM  <complex join, JET version>
#DB=JET#
#DB=MYSQL#
FROM  <complex join, MySQL version>
#DB=MYSQL#
WHERE
    o1.object_type = 'Class'
    AND o1.name LIKE '#WC#<Search Term>#WC#';

Answer 3

Comments with -- and /* */ are working in Enterprise Architect if the comment is not in the first line.
